我正在使用 Spring 来管理 struts 2 动作 bean。我正在尝试从基于 XML 的配置迁移到基于注释的配置。我正在使用 struts2-spring-plugin，以便 struts 获得由 spring 管理的对象的句柄。以下是 myAction 的 applicationContext 文件中的内容。

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
      http://www.springframework.org/schema/beans http://www.springframework.org/schema
      /beans/spring-beans-3.0.xsd
      http://www.springframework.org/schema/context http://www.springframework.org
      /schema/context/spring-context-3.0.xsd">
    <context:annotation-config />
    <bean id="myAction123" class="com.action.MyAction" scope="prototype"></bean>
</beans>

在 struts2-tiles 配置文件中，我定义了请求映射。此映射使用对 spring 创建的 bean 的引用。class属性指的是spring bean定义中定义的id属性。

    <action name="myAction_*" method="{1}" class="myAction123">
        <result name="success" type="tiles">action.request.view</result>
    </action>

Action 类注释如下：

@Controller
public class MyAction {

    @Autowired
    public MyService myService;

    public MyService getMyService() {
        return myService;
    }

    public void setMyService(MyService myService) {
        this.myService = myService;
    }

    public String doSearch() {
        /* ... */
    }
}

请在下面找到堆栈跟踪，当我删除弹簧动作 bean 引用时由 struts 抛出。

我了解我没有放置正确的注释，这是导致此问题的原因。尽管我已经尝试阅读了很多关于这个的内容，但我仍然对迁移这个特定部分感到困惑。我无法确定我是否会为此使用 struts 2 注释或 spring 注释。任何帮助表示赞赏。谢谢你。

您还需要这条线

<context:component-scan base-package="my.package.path" />

在你的 application-context.xml 文件中告诉 Spring 去哪里寻找注释。使用 @Controller 注解没有任何问题。
